Abstract

An inkjet application device (10) has an optical sensor (20) and a control section (30). The optical sensor (20) has a light emission section (32) for emitting detection light (100) so that the light crosses the route of movement of liquid drops and also has a light receiving section (34) for receiving the detection light (100). The optical sensor (20) emits and receives the detection light (100) at a first position and a second position. At the first position, at least a part of the detection light (100) is blocked by a nozzle plate (26). The second position is located below the nozzle plate (26) at a distance corresponding to the distance between the nozzle plate (26) and an object to be treated. The control section (30) determines, based on conditions of reception of light by the light receiving section (34), whether or not there is an object interrupting between the light emission section (32) and the light receiving section (34).
